Calcined Alumina - Digitalfire

Calcined (or alpha) alumina is made by roasting a source alumina powder at 1200-1300C to convert it to pure Al 2 O 3 (when calcined near 2000C large hexagonal, elongated tablet shaped crystals form as "Tabular Alumina"). The alpha form is the densest and most stable crystalline form of alumina.

Calcined Kaolin - Digitalfire

Calcined kaolin has an important use in ceramic glazes. Al 2 O 3 is essential to the chemistry of the vast majority of glazes and its most readily-meltable natural supplier is feldspars, however they most often oversupply KNaO in providing the needed Al 2 O 3. Raw kaolin is an ideal second or even primary source of Al 2 O 3.
